Hi Douglas, Just bumping into this thread.

But, that would mean no patches applied to your production system during those six months. If you were to build a new release(8) any time -stable changes (and you should), then it'd be more. Any update between upgrades takes significantly less time than an upgrade. HTH... Nico
